|
|
|
|
|
accepted by the parser, even though the GL_ARB_vertex_blend and

<h2>Internal code changes</h2>
|
|
|
|
|
|
|
|
|
|
<p>
|
|
|
|
|
A number of Mesa program-related structs were renamed.
|
|
|
|
|
For example <i>struct vertex_program</i> is now <i>struct gl_vertex_program</i>.
|
|
|
|
|
All the effected drivers have been updated.
|
|
|
|
|
</p>
|
|
|
|
|
|
|
|
|
|
<p>Ian Romanick updated the GL API dispatch code in a number of ways.
|
|
|
|
|
First, many old/unused extensions were removed.
|
|
|
|
|
Second, the static entrypoints for some extensions were removed.
|
|
|
|
|
This means GL function pointers will have to be used more often
|
|
|
|
|
(e.g. use glXGetProcAddressARB()).
|
|
|
|
|
